There's an interesting essay in the Armed Forces Journal (which, no doubt, you all read. I only spotted it via Boing Boing) about the negative influence of Powerpoint in decision making. The premise is that the shift away from briefing papers to Powerpoint presentations changes how decision are made for the worse. Much of the points the author argues are as relevant for teaching as decision making. I'd get a coffee and read it, if I was you.
One of the points made was how instead of a short paper being circulated before a meeting where a decision was to be made, much time was spent in the meeting going through the powerpoint slides. Thus people did not review the material in advance, or in the level of depth, or have time to reflect on it before the meeting where the decision was made. Instead of having, say, 20 minutes to discuss an issue and make a decision, there was a 15 minute powerpoint, then 5 minutes to discuss and decide.
And in lectures, we spend 55 minutes in Powerpoint, and zero time in discussion and reflection...
Are the lessons applicable? Could we expect students to review a couple of pages of material before a 'lecture'? Can we expect them then to participate in a discussion of the material, instead of simply listening and writing it all down? Probably not, but should we expect more of them? If we, as teachers, up our game, will they, as students, do the same?
